1. Assume that the country of Rankinland is currently in recession.
(a) Assume that Rankinland produces only food and clothing. Draw a correctly labeled
production possibilities curve for Rankinland. Show a point that could represent the
current output combination and label it A.

Nominal I.R.
(b) Assume the Central Bank of Rankinland pursues
an expansionary monetary policy.
(i) Identify the open-market operation that the
Central Bank would use.
(ii) Draw a correctly labeled money market graph
and show the short-run effect of the expansionary

(iii) Assuming no change to the price level, what happens to the real interest rate as a
result of the expansionary monetary policy? Explain.
(iv) Given your answer to part (b)(iii) regarding the real interest rate, what happens to
the real gross domestic product (GDP) in the short run? Explain.
(c) Suppose Rankinland has a current account deficit. Rankinland’s currency is called
the bera.
(i) What will initially happen to the current account deficit in Rankinland solely due
to the change in the real GDP from part (b)(iv) ? Explain.
(ii) What will happen to the international value of the bera solely due to the change
in the real GDP from part (b)(iv)? Explain.
2. The following is a simplified balance sheet for Mi Tierra Bank in the United States.
Mi Tierra Bank
Assets
Liabilities
Required Reserves $10,000
Demand Deposits $100,000
Excess Reserves
$5,000
Loans
$85,000
Owner’s Equity $0
(a) What is the reserve requirement?
(b) Assume that Luis withdraws $5,000 in cash from his checking account at Mi Tierra Bank.
(i) By how much will Mi Tierra Bank’s reserves change based on Luis’ withdrawal?
(ii) What is the initial effect of the withdrawal on the M1 measure of money supply? Explain.
(iii) As a result of the withdrawal, what is the new value of excess reserves on the balance
sheet of Mi Tierra Bank based on the reserve requirement from part (a)?
(c) Assume that the next day John withdraws from Mi Tierra Bank an amount that exceeds the
bank’s excess reserves. Assuming that no loans are called in, how can Mi Tierra Bank cover
its required reserves?
3. Assume the economy of Andersonland is in a long-run equilibrium with full employment.
In the short run, nominal wages are fixed.
(a) Draw a correctly labeled graph of SRAS, LRAS, and AD. Show the following.
(i) Equilibrium output, labeled Y1
(ii) Equilibrium price level, labeled PL1
(b) Assume that there is an increase in exports from
Andersonland. On your graph in part (a), show the
effect of higher exports on the equilibrium in the SR,
labeling the new equilibrium output and PL Y2 and
PL
PL2, respectively.
(c) Based on your answer in part (b), what is the impact
of higher exports on real wages in the short run? Explain. PL1

(d) As a result of the increase in exports, export-oriented industries in Andersonland
increase expenditures on new container ships and equipment.
(i) What component of aggregate demand will change?
